How high is the genetic probability of back psoriasis

summary

My big cousin has been suffering from psoriasis for two years, and several white plaques have grown on her arms. When it is serious, there will be peeling symptoms. For patients with psoriasis, early detection and early treatment should be done. Now I will tell you about the genetic probability of back psoriasis.

How high is the genetic probability of back psoriasis

First of all: psoriasis has a certain genetic risk. In general, if both parents are psoriasis patients, the incidence rate of children is 50% to 66%. If only one side of the parents is psoriasis, the incidence rate of children is about 16.4%.

Secondly: in terms of the genetic proportion in China, the national epidemiological survey of psoriasis showed that 32% of the patients had a family history of psoriasis, and the mode of inheritance was autosomal dominant inheritance, with 20% of the exons.

Finally: there are psoriasis patients in their families, that is, the investigation of genetic genealogy. In the investigation reports at home and abroad, about 10% - 30% of the patients have a family history of psoriasis. In the long-term follow-up survey of 943 patients, 279 patients have a family history of psoriasis, accounting for 29.5%.

matters needing attention

For patients with psoriasis, we should have a persevere attitude to face the treatment of this disease and cooperate actively. Both parents are suffering from this disease. The incidence rate of their children is increased to seventy percent. The onset of the disease is serious and the psoriasis patients with family history account for 30%-50% of the total number of psoriasis patients. This is internationally recognized data.
